Abstract (en)
The socket has a main body (11) comprising an internal passage (20) for fluid, and a movable joint (16) cooperating with a spring (15) for permitting coupling and decoupling of the socket on an output connection of a fluid distribution valve. A fluid reverse running stop (1) is arranged on the internal passage and permits to oppose all circulation of the fluid in the internal passage in the direction of the output connection, in which the socket is connected. Independent claims are also included for the following: (1) an assembly formed from a connector socket connected to a distribution valve (2) a method for extracting fluid.
